LG Refrigerator Uneven Cooling or Frost Buildup? Fan Grille Assembly AEB72913929 – Fix Airflow Fast

If your LG or Kenmore Elite refrigerator has uneven temperatures, frost accumulating on the back wall, or the fresh food section is warmer than the freezer, the evaporator fan grille assembly is a common cause. In most LG French door refrigerators, the fan grille assembly channels and directs cold air from the evaporator fan across the coils and into both compartments. When it cracks, warps, or breaks — often from ice expansion or physical impact — airflow becomes uneven, temperatures fluctuate, and the compressor runs longer to compensate. ⚡ Common failure point in LG-built French door refrigerators. Part AEB72913929 is the genuine OEM replacement fan grille assembly that restores proper airflow distribution — no modifications required.

❓ Is This the Right Part?

This is the correct fix if ALL of the following are true:

• ✔ Refrigerator has power and the compressor is running
• ✔ Evaporator fan motor is confirmed working — audible hum from the freezer section
• ✔ Defrost system is functioning — no heavy ice buildup on the evaporator coils themselves
• ✔ Existing fan grille is visibly cracked, broken, or has missing sections
• ✔ ONLY problem is uneven airflow, inconsistent temperatures, or poor cold air distribution between compartments

🔧 Common Symptoms

• Fresh food section warmer than set temperature while freezer stays cold — most common, what customers search
• Frost or ice buildup on the back wall of the freezer compartment
• Uneven temperatures across shelves — some areas cold, others warm
• Visible cracks, broken tabs, or missing sections on the existing fan grille
• Er FF or airflow-related error code displayed on the control panel
• Compressor running continuously as the unit struggles to maintain set temperatures

✔ If these symptoms match, this is the most likely failed component in the system.

✔ In most cases, replacing this fan grille assembly restores even airflow and consistent temperatures immediately.
